CONCRETE

Definitions
Concrete
Is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stonelike, water-and-fire-resisting solid of great compressive but low tensile strength.

Precast-concrete constructionEmploys bricks, slabs, and supports made under optimal factory conditions to increase waterproofing and solidity, to decrease time and cost in erection, and to reduce expansion and contractions.

prestressed concrete
Provides bearing members into which reinforcement is set under tension to produce a live force to resist a particular load. Since the member acts like a spring, it can carry a greater load than an unstressed member of the same size.

Tilt wall construction and tilt up panel construction are two names to call the same construction technology.
Tilt wall construction is based on the formation of walls, in the job site, concrete panels is called, is because this form of work. The process of precast building, although similar to tilt wall construction, to have differences. The contractors do not have to abstain during the working of climatic changes because the precast is poured inside.
Is important that Tilt-up buildings and offers more flexibility in this is preferred sites where the weather allows it.

CONCLUSION OF CONCRETE Concrete is important because this is practical and effective as material of construction. Nowadays is the most used materials everywhere, and this is very important to construction. In the future it is possible that concrete will be used as a combination with other materials to make it more interesting and expand its uses.
